A deep sea AUV "MR-X1" for scientific work

Abstract

Since 2000, JAMSTEC has been developing an AUV (length: 2.5 m, weight in the air: 800 kg), MR-X1, with a shape like the head of a fish. The maximum depth of the AUV is 4,200 m and its operating time is approximately 15 hours with a Li-ion battery unit. Five thrusters are equipped for high maneuverability. A TV camera, a side scan sonar, and a manipulator are equipped for various scientific works. MR-X1 has three operation modes: an autonomous mode, an UROV mode, and a wireless (acoustic/radio) control mode. The development goal of the MR-X1 is achievement of the working robot with high intelligence for detailed ocean investigation, installation of observation equipment on the sea floor and so on.
